Convert to the much saner new idr interface.
Only compile tested.
Signed-off-by: Tejun Heo <tj@kernel.org> Cc: David Woodhouse <dwmw2@infradead.org> Cc: linux-mtd@lists.infradead.org --- This patch depends on an earlier idr changes and I think it would be best to route these together through -mm. Please holler if there's any objection. Thanks.
